Claims (1)
- 本体に備わり前記本体を移動させるための移動手段、前記本体に設けられた変位センサー及び前記変位センサーが検出した変位に基づいて前記移動手段の制御を行う移動制御手段を備えた自走式移動車において、
前記移動制御手段は、前記移動手段による前記自走式移動車の移動パターンを前後直進移動又はその場回転移動に指定し、
前記変位センサーは、前記自走式移動車が前記その場回転移動をするときの回転中心軸線上以外の位置に配置されて走行床面を撮影する1つの光学式変位センサーであり、前記回転中心軸線を通る車体前後中心線に一致する前後軸と、前記回転中心軸線を通り前記車体前後中心線に直交する車体左右中心線と平行な左右軸とから成る直交2軸を変位検出軸として有しており、
更に、前記移動制御手段は、前記光学式変位センサーが撮影した前記走行床面の画像の変動データに基づいて、前記自走式移動車が前記前後直進移動をするときに前記前後軸方向に検出される前記変位から前後直進距離を求め、前記自走式移動車が前記その場回転移動をするときに前記左右軸方向に検出される微小な前記変位について前記回転中心軸線の回りに見込む角度を微小な前記変位毎について逐次積算することでその場旋回角度を求めることを特徴とする自走式移動車。
